Title: Dechlorination filter
Inventor: AKIHAMA TSUGIHIKO
IPC: C02F1/70
Filed: 1994-04-14
Abstract: PURPOSE:To make a filter economical and have improved treatment function as the whole filter by forming a reductive and reactive filtering agent which can decompose remaining chlorine in tap water into a column shape and installing one or more water passing hollow routes to which water can be led directly in the column. CONSTITUTION:Calcium sulfite, a reductive and reactive filtering agent 2 to decompose remaining chlorine in tap water, is formed into a column-like shape to give a column body 4 and a plurality of water passing hollow routes 3 to which water can be led directly in up and down directions are installed to give a dechlorination filter 1. When tap water is led to the filter 1, the water dissolves the filtering agent 2 by passing the filtering agent 2 in the column body 4 and, by the filtering agent 2, remaining chlorine in the tap water is decomposed and the water quality is improved. At that time, since a part of the tap water is directly led to the water passing route 3 and passes therethrough, remaining chlorine is not decomposed but the water passes the filtering agent 2 at a water leading outlet and is mixed with tap water in which the filtering agent 2 is dissolved excessively and thus the remaining chlorine can be decomposed.

Title: Photoelectric converter
Inventor: AOKI YOSHITAKA
IPC: H01L31/105
Filed: 1984-05-18
Abstract: PURPOSE:To improve the resolution of a photoelectric converter in a lateral direction by providing a photoelectric conversion layer having a plurality of signal sampling electrodes of regions and a blocking layer bonded to the electrodes or regions and selectively separated. CONSTITUTION:Signal sampling electrodes or regions 8 are selectively disposed on a substrate 7 of semiconductor. After an amorphous Si layer is formed, N type impurity is implanted to form a blocking layer 15. Then, an i-type layer 10 and a P type layer 11 made of amorphous Si are accumulated. Thereafter, a transparent electrode 12 is laminated. According to this configuration, since the layer 15 is separated, the diffusion of signal charge in the lateral direction is decided by the layer 10 to reduce the movement of the signal charge between the electrodes or regions 8, thereby decreasing the resistance of the layer 15. Accordingly, the resolution of lateral direction can be improved to prevent holes from implanting to reduce dark current.

Filed: 1978-08-22
Abstract: PURPOSE: To perform an on-line measurement of each film thickness of a multilayer transmission material continuously without contact by using a Michelson interference meter utilizing a white light.  
     CONSTITUTION: The light from light source 1 becomes a parallel light and reaches beam splitter 3 and is divided into light fluxes R 1  and R 2 . Light flux R 1  is incident onto sample 4 and is reflected by fixed mirror 6 and reaches detector 11. At this time, since light flux R 1  is reflected for every film layer face of measured sample 4, the light incident onto detector 11 becomes composite light fluxes defferent in phase. The other divided light flux R 2  is reflected by movable mirror 7 and reaches detector 11 through beam splitter 3. Movable mirror 7 is positioned by differential transformer 10 and is driven by speaker 9 while being prevented from transversal vibration by air bearing 8. Then, since a light path difference is generated in light flux R 2 , the film thickness of each layer can be detected by measuring the interference geterated between light fluxes R 1  and R 2 .

Title: Data reading method
Inventor: OTSUKA MASAKI
IPC: G06F3/06
Filed: 1992-04-22
Abstract: PURPOSE:To prevent access time from being increased in the case of reading error data from a storage medium and transferring them to a host device by deciding whether block data are erased from a buffer memory or not based on an identifier. CONSTITUTION:It is identified by the identifier in a managing table 6 whether the block data stored in a buffer memory 3 are restored by using parity blocks or not and after the block data are transferred from the buffer memory 3 to the host device, it is decided based on the identifier whether the block data are erased from the buffer memory 3 or not. Therefore, since the block data restored by using a parity group can be held in the buffer memory 3 even after they are transferred to the host device, the block data temporarily restored by using the parity blocks can be immediately transferred without performing restorage processing even when there is any reading instruction later, and the reduction of reading speed can be suppressed.

Title: Cleaning blade and its production
Inventor: YAMAMOTO TAKAO
IPC: G03G21/00
Filed: 1986-04-30
Abstract: PURPOSE:To securely adhere a soft blade member made of a synthetic resin to a plate-shaped holding member with high accuracy by melting an adhesive film by high-frequency induction heating to adhered said soft blade member and plate-shaped holding member. CONSTITUTION:The soft blade member 4' made of the synthetic resin and the plate-shaped holding member 3' themselves are not heated and only the adhesive film 5 is heated to melt and to provide an adhesive effect in order to adhere the soft blade member 4' and the plate-shaped holding member 3' by melting the adhesive film by high-frequency induction heating. The thermal deformation is, therefore, not induced in both members and the high-strength adhesion with high accuracy is realized in a short period. The resultant cleaning blade has the adhesive agent layer 5 into which magnetic powder is incorporated. Since the magnetic powder provides the effect of releasing static electricity, the static electricity generated during the use of the cleaning blade is efficiently released through the adhesive agent layer 5, by which the ill effects due to the stagnating static electricity is averted.

Filed: 1981-06-30
Abstract: PURPOSE:To obtain a directional pattern of less minor lobe, by making the lift- off of an eddy current generating coil smaller in the inside and larger in the outside. CONSTITUTION:An eddy current generating coil 3a arranged on the lower face of an iron core 1 is formed to a shape like a bowl so that its lift-off is smaller in the coil inside and is larger in the outside. When a DC is flowed to a magnetic field generating coil 2 wound around the iron core 1, a magnetic field B is generated near the surface of a meterial 4 to be examined. Meanwhile, when a current flowed as shown in (i) of a figure is flowed to the generating coil 3a, an eddy current where an inside densityII is higher than an outside densityIphi is generated near the surface of the material 4 to be examined. Since the magnetic field B is uniform, an inside force FI of a force F generated on the surface of the material to be examined is larger than an outside force Fphi. Since the force acting upon the peripheral part of the surface of the material to be examined is smaller than that acting upon the center, the minor lobe becomes smaller than the conventional that. It is propagated as transversal waves.
